International Water-Guard Industries Inc. (IWG) is the world’s dominant provider of flight-certified water treatment units.
Since 1982, IWG has been the water treatment solutions provider to Corporate, VIP, and Military transport operators around the world. Major business jet manufacturers now offer IWG’s products as either a standard installation at the factory, or as a customer option, including: Bombardier, Dassault Falcon, Gulfstream, and Raytheon.
Today, more than 1000 of IWG’s flight-certified units are shielding aircraft passengers and crew around the world from waterborne disease.
IWG currently produces four models: the NPS-A6, NPS-A4, NPS-A3, and NPS-A2 aircraft water treatment units. All were designed from the outset to exceed the demands of aircraft use, and provide the highest level of water disinfection. IWG units all incorporate ultraviolet light disinfection to eliminate harmful micro-organisms, and use the National Sanitation Foundation’s highest potable water treatment standard (Standard 55, Class A) as a benchmark.
